2. Description of the Prior Art

There are many applications where a portable source of power is desired.These applications include the operation of many rotary devices such asportable gardening tools including hedge trimmers, weed cutters, smallchain, reciprocating or rotating saws, and the like. Such devices areused while the user thereof is mobile. These devices are often driven bya small internal combustion engine using gasoline as the energy sourceand having a small tank for the gasoline as part of the equipment andproviding a rotary output through a rotating drive shaft driven by theinternal combustion engine to drive the particular device. As such, theyrequire the storage of gasoline for the continued operation thereof inorder to periodically refill the small gasoline tank. However, thestorage of gasoline is highly restricted as to the type of container inwhich it may be stored, the places where it may be stored, the amountthat may be stored and the environmental conditions under which it maybe stored.

Another application of portable sources of power is in the field ofdevices that, while portable, are generally stationary during use. Thisfield of devices includes portable electric generators utilized foremergency power or to provide electrical energy in locations where otherelectrical energy is not available. Many of these portable electricalpower generators are driven by an internal combustion engine. The largertypes of these portable electric power generators as carried inemergency vehicles of various types utilize gasoline or diesel poweredengines with comparatively large storage supplies of the gasoline ordiesel oil. Such devices are, of course, large and cumbersome and notadapted to be a readily portable device that may be easily carried byone person and transported from location to location.

However, there is a demand for an electric power generator that is smalland light enough to be moved by one person from location to location andstill provide a moderate amount of electrical power. These smallelectrical power generators are often driven by a small, light weightinternal combustion engine. In this class of small, light weightinternal combustion engine driven electrical generators it is oftendesired to store such device, either permanently or temporarily in thehome, garage, vehicle or other location and also to store acomparatively large amount of fuel for use therein. In the situation ofan electrical power outage in a residence, a small electrical powergenerator may be utilized to power a radio, recharge a cell phone orother such device, power a hot plate for cooking, provide illuminationor for other desired activities. Other uses of a small internalcombustion engine drive electrical generator are in campsites, on boatswhich do not have any other type of electrical power, and may otherpurposes.

The internal combustion engine that have heretofore been proposed forthese small internal combustion engine driven electrical generators havebeen single cylinder, two cycle, engines in which the compression hasbeen in the cylinder located in the crankcase thereof.

To meet these desiderata it is necessary that the fuel to power theinternal combustion engine be of the type and in the condition that itmay be stored in virtually any desired amount at the storage location ofthe engine powered electrical generator. The use of LPG is one type offuel that may be utilized in an internal combustion engine in place ofthe gasoline or diesel to power the internal combustion engine that isutilized to drive the electrical generator, or other engine drivendevice. The LPG containers are pressurized so that the gas therein isconverted to the liquid state and, as such, has an amount of fluid inthe gas state above the vertically top level of the fluid in the liquidstate.

One type of LPG storage bottle that has been proposed to provide powerfor these small internal combustion engine driven devices is a smallcontainer holding approximately 1 to 2 pounds of LPG contained in thebottle. These bottles have heretofore been utilized in various campingapplications and are widely available.

In some of the prior art configurations, an LPG container was utilizedand the LPG container required a particular rotational orientation aboutthe long axis thereof in order to feed the gas therefrom because of agenerally right angle bended feed tube in the container through whichthe gas flows to regions external the LPG container. Such aconfiguration limits the utility of such a device.

One very well known brand of such LPG bottles is the small LPGcontainers which are generally known to the public as Coleman Bottles.The Coleman Bottles are on the order of three and one half inches indiameter and on the order of seven and one half inches in axial lengthand contain about one to two pounds of the LPG. The Coleman Bottles comeequipped with a standard threaded adapter for ready threading into autilizing device and do not have any preferred orientation of rotationabout the long axis thereof with respect to the device into which it isthreaded. The adapter has an internal disconnect coupling forappropriate connection into a matching disconnect coupling which allowsthe flow of gas from the bottle when connected and prevents the flow ofgas therefrom when disconnected. The Coleman Bottles are also providedwith a built in pressure relief valve for safety in the event of overpressurization. The Coleman Bottles contain such a limited amount of LPGthat a plurality of such bottles generally may, within the present lawsand regulations, be stored in the home, in the garage or carried in avehicle thus making them attractive as a substitute for use in manygasoline or diesel oil powered applications. However, the gas flow rateof the gas from the LPG in a Coleman Bottle is limited because of thecomparatively small surface area of the LPG from which the gas isgenerated. In the event that too high a gas flow rate is demanded fromthe LPG in a Coleman Bottle, the LPG will freeze and thus effectivelyend the generation of the gas at usable flow rates from the LPG.Consequently, despite the attractiveness of the Coleman Bottles for usein many devices, the use of the Coleman Bottles has generally beenlimited to very low power requirement applications and have not beenadapted for use in providing the energy for powering an internalcombustion engine utilized to drive an electrical generator or otherportable engine driven devices.

Thus, there has long been a need for a suitable arrangement in which astandard, readily available Coleman Bottle is utilized in an applicationin which power sufficient to drive a small electrical generator or othersmall portable engine driven devices is demanded.

Accordingly, it is an object of the present invention to provide animproved portable internal combustion engine driven device in which theengine is powered by LPG.

It is another object of the present device to provide an improvedportable internal combustion engine driven device in which the engine ispowered by LPG and the LPG is in a container having a comparativelysmall amount of LPG.

It is another object of the present device to provide an improvedportable internal combustion engine driven device in which the engine ispowered by LPG and the LPG is in a container having a comparativelysmall amount of LPG and the LPG container may be rotated about its axisto any desired position for operation and does not require a particularrotational position about its axis for operation.

It is yet another object of the present invention to provide an improvedportable internal combustion engine driven device in which the engine ispowered by LPG and the LPG is in a container having a comparativelysmall amount of LPG and in which a comparatively large and continuousflow of gas from the LPG in the container is obtainable.

It is a still further object of the present invention to provide animproved portable internal combustion engine driven device in which theengine is powered by LPG and the LPG is in a container having acomparatively small amount of LPG and the mounting of the LPG containerwith respect to the internal combustion engine allows a comparativelylarge and continuous flow of gas from the LPG in the container.

SUMMARY OF THE INVENTION

The above and other objects of the present invention are achieved, in apreferred embodiment thereof, in an internal combustion engine drivendevice which for purposes of describing this embodiment may be anelectrical energy generator. The internal combustion engine may be afour stroke, two stroke with appropriate oil injection, single cylinderair or liquid cooled engine, though larger types of engines may beutilized as desired for particular applications. The internal combustionengine may have an inertial or pull type starter to initiate operationthereof and such engines are readily available. The cylinder of theinternal combustion engine is contained in a crankcase and the movementof the piston in the cylinder drives a crankshaft which is connected tothe device to be driven such as the electrical generator. The combustionof the gas-air mixture in the cylinder of the internal combustion enginegenerates heat which heats the cylinder and crankcase of the engine.Further, the operation of the engine also vibrates the engine and allthe structure associated with therewith.

The engine has a carburetor in which the gas is mixed with air toprovide the explosive mixture that is introduced into the cylinder. Theengine is provided with a spark plug to initiate the combustion of thegas-air mixture in the cylinder.

In accordance with the principals of the present invention a mountingplate is adjacent the crankcase of the engine and is coupled thereto.The mounting plate receives both heat from the crankcase and is vibratedby the vibration of the engine.

The gas provided to the carburetor is gas from the LPG contained in aColeman Bottle arrangement of one or more Coleman Bottles. The ColemanBottle type LPG container (whether called a Coleman Bottles or soldunder any other brand name) in the arrangement is mounted on themounting plate connected to the crankcase of the internal combustionengine to be in heat transfer and vibration transfer relationshipthereto in a preferred orientation with respect to the horizontal. TheColeman Bottle may be of the configuration illustrated in U.S. designpatent D295886. The Coleman Bottles may contain, in the smaller versionsthereof, liquified petroleum gas on the order of 14 to 16 ounces. Suchsize LPG containers are the general type preferred for usage in theembodiments of the present invention. The preferred orientation is withthe long axis of the Coleman Bottle LPG container at an angle of between14° and 16°, with 15° being desired, for the present configuration ofthe Coleman Bottles. This angular orientation provides the very unusualand unexpected result of maximizing the gas flow and preventing the flowof liquid LPG from the Coleman Bottles. Since the Coleman Bottles arenot filled to the top of the bottle with the LPG but have apredetermined and generally uniform from bottle to bottle volume of gasabove the top surface of the LPG The selected angular orientation of theColeman Bottles with respect to the horizontal is such that the surfacearea of the LPG is maximized but the outlet of the Coleman Bottles isvertically above the top surface of the LPG. Such orientation of theColeman Bottles not only maximizes the usable surface area of the LPGfrom which the gas state is generated but also prevent the flow of LPGin the liquid state therefrom. The preferred angular orientation withrespect to the horizontal may be selected for other LPG containers whichmay be utilized in other applications to achieve the unusual and novelconfiguration for evaporation of the gas from the liquid LPG. TheColeman Bottles have the additional advantage of being free from anyrequirement for a particular rotational position about its long axis foroperation. That is, for the Coleman Bottles mounted as described herein,the Coleman Bottles may be in any rotational position about its axis andstill provide operation.

The above described mounting of the Coleman Bottles on the mountingplate to be in thermal transfer relationship thereto for receiving heatas generated in the cylinder of the internal combustion engine as wellas receiving vibration therefrom uniquely allows the continuous flow oflarger amounts of gas from the LPG to thereby allow the powering oflarger internal combustion engines and demand devices. The heattransferred to the Coleman Bottles heats the LPG contained therein toincrease the evaporation of gas therefrom. The heat thus transferred tothe LPG tends to keep the temperature of the liquid LPG above thefreezing point even though comparatively larger amounts of gas areevaporated therefrom. The direct transfer of heat from the engine to theColeman bottle and thus to the LPG therein has a dual benefit: the heatkeeps the LPG from freezing and aids in cooling the internal combustionengine during the operation thereof. The transmittal of vibration of theColeman Bottle by the operation of the engine also agitates the LPG tothus increase the effective surface area thereof thereby allowing evengreater flow of gas therefrom and the agitation also helps in preventingthe LPG from freezing.

The internal combustion engine has a rotating crankshaft that is drivenby the operation of the piston in the cylinder and the crankshaft isconnected to any desired device that is to be powered. For purposes ofexplanation of the principles of the present invention, the preferredembodiment of the invention is described and shown herein as having anelectric generator driven by the internal combustion engine. However,many other devices may be driven by the internal combustion engine instructure incorporating the principles of the present invention.

The generator is driven by the internal combustion engine and provideselectrical power. The electrical power may be alternating current and/ormay also be direct current. Suitable receptacles for allowing plug inconnection at the receptacles to electric powered devices are provided.

In order to provide even greater flow of gas, two or more ColemanBottles may be mounted on the internal combustion engine and connectedtogether to provide a single gas flow outlet therefrom.

In some applications of the preferred embodiment of the presentinvention it may be desired to utilize other gas powered devices of thetype commonly used in many outdoor camping applications and the like.Such gas operated illumination, cooking, heating and similar devicesgenerally have a built in pressure or flow regulator. A separate gasflow outlet tube may be provided from the Coleman Bottle to allowattachment and operation of these devices either independently orsimultaneously with the operation of the electric generator.

In other applications of the present invention, gas powered internalcombustion engine may be utilized to power such diverse implements asvarious gardening tools such as leaf blowers, edge trimmers, mowers, andthe like as well as other devices where a safe, portable source of poweris required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawing and in particular FIGS. 1 and 2, there isillustrated in FIG. 1 a block diagram of a preferred embodiment,generally designated 10, of a portable gas powered internal combustionengine arrangement and in FIG. 2 there is illustrated a semi schematicrepresentation of a preferred LPG container 12 as utilized in theembodiment 10. In the LPG container 12 shown in FIG. 2, which inpreferred embodiments of the present invention is a Coleman Bottle orsimilar storage container, there is a liquefied gas under pressureindicated at 14 and also gas phase 16 as evaporated from the liquifiedgas 14. The gas 16 flows from the LPG container 12 through a conduitindicated at 18. Since the pressure of the gas 16 in the LPG container12 is much greater than is desired for use in the embodiment 10, the gasflow through conduit 18 is directed to a pressure regulator 20. Thepressure regulator 20 regulates the pressure of the gas 16 flowingtherethrough to a value on the order of 0.217 psi to 0.365 psi which isthe range of pressures that can be utilized for the internal combustionengine 22 as described below, though higher or lower pressures of thegas may be utilized as desired for particular applications.

The gas 16 may also be directed to flow from the conduit 18 throughconduit 19 to an auxiliary gas powered device 21 such as an illuminationdevice, cooking device or the like. Such devices are well known and ingeneral have a built in pressure regulator or flow control to regulatethe pressure or flow of the gas 16 to a value that compatible with thedevice 21.

The gas 16 flowing from the pressure regulator 20 is directed through aconduit 23 into a carburetor 24 that is part of the internal combustionengine 22. The carburetor 24 has an air intake as indicated at 26. Thecarburetor 24 mixes the gas 16 with the air and provides the mixture tothe cylinder 28 of the internal combustion engine 22 in a manner wellknown. The internal combustion engine 22 has a rotating output shaft 30.In the embodiment 10 the rotating output shaft drives an electricgenerator 32. The electric generator 32 provides electric energy asindicated at 34 and may be, for example in the power range of 300 to1000 watts though larger power generators may be utilized in otherapplications. The electric energy may, if desired, be directed toprovide 12 volt DC current as indicted at 36 or may be passed into aninverter 38 for conversion to 120 volts AC, 60 cycle as indicted at 40.

As noted above, the internal combustion engine 22 may be a four stroke,or two stroke with appropriate oil injection, air or liquid cooledengine, though in other applications a larger engine may utilized asdesired. During the operation of the internal combustion engine 22, thecombustion of the gas 16 and air mixture therein in the cylinder thereofgenerates heat and also vibrates the engine 22. As described below ingreater detail, these two factors which are always occurring during theoperation of an internal combustion engine are uniquely andadvantageously utilized in the operation of the various embodiments ofthe present invention.

FIG. 2 illustrates in schematic representation, a typical LPG container12 such as a Coleman Bottle. The LPG container 12 may be of the typemanufactured by various entities and may come in a variety of sizes. Ingeneral, such LPG containers are provided with a built in safetypressure relief valve 42 to allow the venting of the gas 16 in the eventthat the pressure thereof exceeds a predetermined value. In theembodiment 10 the LPG container 12 as shown schematically in FIG. 1 maybe comprised of a plurality of individual LPG containers joined togetherto discharge gas 16 through a single outlet such as conduit 18. FIG. 3schematically shows three LPG containers 12 a, 12 b and 12 c joinedtogether by a manifold 18′ to discharge gas 16 through the singleconduit 18.

FIG. 4 illustrates an exploded view of the assembly of the LPG bottle 12and the internal combustion engine 22. The carburetor 24 is mounted onthe side of the cylinder 28 atop the crankcase 44. There is provided aspark plug 46 which provides the spark required to ignite the gas/airmixture that is received in the cylinder 28 from the carburetor 24 todrive the output shaft 30. An inertia or recoil type starter 48 isprovided to start the operation of the internal combustion engine 22.

A front plate 50 is mounted on the crankcase 44 by bolts 52 a, 52 b, 52c and 52 d. The front plate 50 is provided with a connector 56 that isadapted to engage the output connection 12′ of the LPG tank 12. Amounting bracket 58 is rigidly connected to the crankcase 44 of theinternal combustion engine 22 and to the front plate 50 by bolts 60 a,60 b, 60 c and 60 d to be in heat receiving and vibration receivingrelationship to the internal combustion engine 22. The mounting bracket58 has a strap 62 which is provided with an over center fastener 64 andthe strap 62 is adapted to receive the LPG container 12 therein for snugretention in the cavity 66 when the over center fastener 64 is closed.As noted above, when the LPG container 12 is mounted in the cavity 66the connector 56 of front plate 50 engages the output connection 12′ toallow the flow of gas 16 through the conduit 18 and/or 19.

Since there may be some variation in the size of LPG containersdepending on the amount of LPG stored therein and the size desired by aparticular manufacturer thereof, FIG. 4A shows an LPG container 12A thatmay be utilized in the embodiment 10 as shown in FIG. 4. An adapter 70is provided which has a cavity 72 therein and the walls 72′ of thecavity 72 are adapted to provide a snug fit on the LPG container 12A.The outer walls 74 of the adapter 70 are substantially the same diameteras the outer diameter of the LPG tank 12 so that there is a tight fit inthe cavity 66 of the mounting bracket 58.

The output shaft 30, in the embodiment 10 is, as described above inconnection with FIG. 1, connected to the electric generator 32. However,as described below in connection with other embodiments of the presentinvention, the output shaft 30 may be connected to any desired type ofdevice that requires a drive engine for operation.

FIG. 5 illustrates the mounting of the LPG tank 12 in preferredembodiments of the present invention. In FIG. 5, the arrow 74 representsthe direction of gravity and the horizontal direction as indicated bythe line 76 is perpendicular to the direction of gravity 74. As is wellknown, the latent heat of vaporization of the gas 16 from the liquifiedgas 14 tends to cool the liquified gas 14 and if too much gas 16 isproduced, the liquified gas 14 will freeze to a solid state. Further,the gas 16 is evaporated from the surface 14′ of the liquified gas 14.Therefore, it is desired to tend to maximize the surface area of theliquefied gas 14 so that the maximum amount of gas 16 may be providedfrom a given size LPG container. However, the more gas 16 that isevaporated from the liquified gas 14, the greater is the chance that theliquified gas 14 will freeze to the solid state and thus end theevaporation of significant amounts of gas 16. In the present invention,as shown in FIG. 5, the LPG container 12 is mounted at an angle A to thehorizontal and the angle A has been found to be on the order of 12° to16° with a preferred angle of 15° for the conventional Coleman BottleLPG container and provides in the angular range that will prevent anyliquified gas 14 from entering the conduit 18 even when the container 12is full. The mounting plate 58 is preferably fabricated from a high heattransfer material such as aluminum so that the maximum amount of heat istransferred by conduction from the engine 22 through the mountingbracket 58 to the wall of the LPG container 12 and thus to the liquifiedgas 14 because of the direct rigid mounting of the mounting bracket 58on the internal combustion engine 22. The heat thus transferred to theLPG container 58 from the engine 22 counteracts the latent heat ofvaporization and tends to prevent the freezing of the liquified gas 14.Further, the vibration of the internal combustion engine 22 agitates thesurface 14′ of the liquified gas 14 thereby increasing the surface areato an amount greater than would occur without the vibration. Suchagitation increases the surface area 14′ of the liquified gas 14 and theconduction of heat to the liquified gas 14 tends to increase the amountof gas 16 that may be generated from the liquified gas 14 for a givensize and configuration of the LPG. However, for LPG containers of adifferent configuration than the Coleman Bottles, a different angularrelationship of the LPG container may be required to maximize thesurface area of the liquified gas 14 but still prevent the discharge ofliquid into the conduit 18 even when the LPG container is full. The useof conductive heat transfer from the engine 22 to the mounting bracket50 also helps cool the internal combustion engine.

As noted above, in the embodiment 10 the output shaft 30 of the internalcombustion engine 22 is connected to an electric generator 32. FIGS. 6through 9 illustrate the configuration of an embodiment 10 that is smalland convenient to carry. As shown on FIG. 6 which is a front view of theembodiment 10 there is a case 80, partially broken away for clarity, inwhich the internal combustion engine 22 and electric generator arecontained. The recoil starter 44 is provided with a pull 44′ foroperation thereof in a well known manner. As shown in FIG. 6 there isprovided a handle 82, partially broken away, for convenient lifting andcarrying of the embodiment 10. Feet 84 may be provided on the bottomportion 82′ of handle 82 for the support of the embodiment 10 on anydesired surface.

As shown most clearly on FIG. 7, the output electrical energy generatedby the electrical generator 32 is provided in both 120 volt AC at dualsocket 90 and two 12 volt DC outlets as indicated at 92.

FIG. 10 illustrates an embodiment 100 of the present invention asutilized to power an trimmer 102. As shown on FIG. 10, there is providedan internal combustion engine 22 powered by gas from an LPG container 12and the internal combustion engine 22 rotates an output shaft 30′ torotate the trimmer. Thus, the internal combustion engine and LPGcontainer replace the gasoline powered engine and gasoline tank oftenutilized in such applications.

FIG. 11 illustrates an embodiment 110 of the present invention in whichan internal combustion engine 22 powered by the gas from an LPGcontainer 12 drives a fan 112 to provide a leaf blower 114. Inembodiment 110 the internal combustion engine 22 and LPG bottle 12replace the gasoline powered internal combustion engine and gasolinestorage tank often utilized in such applications.

As described above, there is provided by the present invention aconvenient and safe internal combustion engine driven by the gasgenerated from the liquefied gas in an LPG container and in which theamount of gas to be drawn from the liquefied gas in the LPG is maximizedby having the LPG container rigidly connected to the internal combustionengine for both direct conductive heat transfer from the internalcombustion engine to the LPG to overcome the cooling due to the latentheat of evaporation of the liquefied gas and to have the internalcombustion engine vibrate the LPG container to increase the effectivesurface area of the liquefied gas. The liquefied gas may be, forexample, propane, butane or the like as packaged by many manufactures invarious shapes and sizes of LPG containers.
